## Abstract Magic angle spinning (MAS) ^13^C NMR was employed to investigate seeds. By combining single pulse excitation (SP) and crossβpolarization (CP) experiments, we showed that both liquid and solid domains of plant seeds (__Arabidopsis thaliana, Lactuca sativa__ and __Pisum sativum__) can be

## Abstract Scleroglucan is a branched poiysaccharide, soluble in water. Solidβstate and solution ^13^C NMR were used to follow the fixation of water molecules on anhydrous scleroglucan and the evolution of the scleroglucanβwater complex from the solid state to the gel and solution state. Determina
p<:yclodc\trin inclusion complexes of 3-aminobenzonitrile. 4-aminobenzonitrile. and adamantane-I-carbonitrile \\ere studied by means of high-resoiution solid-state CP MAS 13C NMR spectroscopy. The interactions between the host and guest molecules are discussed.
Solid poly[(R)-3-hydroxybutyric] acid was examined by high-resolution 13C MAS NMR, differential scanning calorimetry and infrared spectroscopy. The 13C methyl group resonance consists of three components: the rigid amorphous phase, the crystalline phase and the mobile amorphous phase. Spectral decon
High-resolution solid-state magic angle spinning (73)Ge NMR spectra of some organogermanium compounds were measured. Most tetrasubstituted germanes with identical substituents exhibited signals except for one case. Tetrasubstituted germanes with two kinds of different but somewhat similar substituen
